Product Description



mass stock in our factory:




Molybdenum disilicide (MoSi2) heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800C during oxidizing atmosphere. According to your request, our company can produce the products of Pole, "U", "W" and "U"-right angle shapes, etc.


MoSi2 heating element can usually make use of furnace temperature from 1300C to 1800C. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc.. It is an essential ideal element when the products are sintering in the high temperature.


 Max temperature 1800C with firm welding point. The quality can compete with Europe. We are an earliest manufacturer in China to produce MoSi2 heater.


Chemistry Character:

  MoSi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature

2. Notice to Furnace Operation:

 To avoid high current surges may cause damage to MoSi2 heating elements, the recommend starting procedure as following:

Small Furnace (Power 100KW)

Big Furnace (Power 100KW-500KW)

Furnace Temperature .C


Furnace Temperature .C











500-Working Temperature


700-working Temperature


Note: Shifting gear must be done quickly, otherwise high current surges may cause damage. 

Order sample:
d=6mm, c=12mm, Le=200mm, Lu=180mm, a=30mm
Please specify as: dia6/12x200x180x30mm (dia d/cxLexLuxa mm)
d = the diameter of hot zone
c = the diameter of cold zone
Le = the length of hot zone
Lu = the length of cold zone

 Delivery time: one week

 Order Sample of the L Shape Mosi2 Heating Element



 When you place order, please choose suitable type according to your furnace working temperature and kindly tell us the following dimensions


 Order sample:


d=6mm, c=12mm, Le=200mm, Lu=180mm, a=30mm


Please specify as: dia6/12x200x180x30mm (dia d/cxLexLuxa mm)


d = the diameter of hot zone


c = the diameter of cold zone


Le = the length of hot zone


Lu = the length of cold zone


MoSi2 Heating Element's installation: 
The brittleness of MoSi2 heating  element is relative more under the usual temperature, it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector cant be screwed too tightly. 
When temperature of the element is going up,  please twist it tightly again, so the element is not easily broken. (our suggestion: please choose the specialize power connector provided by our company) The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top cant be over 300C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than 50mm between the low end of connector and the upside of the ceramic brick. The Dia.6 element cant be used of 170A for a long time. The Dia.9 element cant be used of 300A for a long time.`
